One end of the embedded screw 5 far away from the sleeve 6 can be fixedly connected with the reinforcing rod vertical to the embedded screw. Therefore, the whole tension (force) bearing capacity of the embedded screw 5 is stronger.

The working principle is as follows: the scaffold body 1 is connected with the shear wall 29 through the outer wall connecting piece 2, and the stability of the scaffold is ensured through the shear wall 29 and the outer wall connecting piece 2. When the embedded part 3 of the external wall connecting piece 2 is embedded in the shear wall 29, because both ends do not exceed the shear wall 29, the embedded part 3 does not need to be cut and the like in the following process. After the scaffold body 1 is used and removed, the sleeve 6 is poured, and the pouring workload and the pouring difficulty are reduced due to the fact that the sleeve 6 is poured.

The utility model discloses a scaffold frame is simple with shear force wall 29's connection structure, and the problem that the built-in fitting 3 of having solved outstanding shear force wall 29 threatens staff's safety and need carry out the cutting to the protruding part of built-in fitting 3 has effectively guaranteed staff's safety, has reduced staff's intensity of labour simultaneously.

Further, as shown in fig. 1 and 2, the threaded connection member 4 includes a connection rod 8, a first thread bushing 9 and a second thread bushing 10, the two ends of the connection rod 8 are respectively provided with an external thread matched with the first thread bushing 9 and the second thread bushing 10, the first thread bushing 9 and the second thread bushing 10 are respectively in threaded connection with the two ends of the connection rod 8, the first thread bushing 9 is in threaded connection with the embedded screw 5, the second thread bushing 10 is in threaded connection with the connection screw 7, and the outer diameter of the first thread bushing 9 is smaller than the inner diameter of the sleeve 6.

The scaffold body 1 is roughly reserved for the distance from the shear wall 29 in the carrying process, and then is connected through the threaded connecting piece 4. And the interval between the two need not to adjust when connecting, satisfies the connection condition through rotating first thread bush 9 and second thread bush 10, and first thread bush 9 rotates towards buried screw 5 direction in advance promptly, and second thread bush 10 rotates towards connecting screw 7 direction, and the distance between this process first thread bush 9 and second thread bush 10 and buried screw 5 and connecting screw 7 reduces gradually, and until the two is connected with buried screw 5 and connecting screw 7 in advance respectively.

Threaded connection piece 4 so sets up and only needs roughly to reserve the distance of scaffold body 1 and shear force wall 29, later connect through threaded connection piece 4 can, avoided the process of accurate calculation scaffold body 1 and shear force wall 29 distance, be favorable to improving scaffold and carry on efficiency.

Further, as shown in fig. 3-6, a self-locking connecting sleeve 11 is slidably sleeved outside an upright rod 20 of the scaffold body 1, two sides of the outside of the connecting sleeve 11 are hinged with connecting rods 12, two sides of the upright rod 20 are respectively hinged with supporting rods 13, a sliding sleeve 14 is slidably sleeved outside the supporting rods 13, one end of each connecting rod 12, which is far away from the connecting sleeve 11, is hinged with the sliding sleeve 14, and the supporting rod 13 is located below the outside of the connecting sleeve 11;
